I'm just wondering what everybody prefers to use when 3D milling with ball mills. My dealer tells me that old school people use step over by distance while new school programmers use the scallop height. Well, I guess I'm old school. I've always used step over by distance. I'm finishing a race tra...
In the images below we'll use a stepover equal to 1/10, 1/5, and 1/3 of the tool diameter to show this correlation. To put real numbers on this, that would be equavalent to a .012, .025, and .042" stepover for a …

Milling Step-over Distance Calculator . In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.

This lesson applies to Vectric VCarve, Aspire, and Cut2D. ... For a stepover if you want a very nice finish, I generally go around 8% for the percentage. That will give you a very nice finish, but it will ...
I have the model "Last Supper Dish" and am trying to work out the best stepover size . The carve size is 400mm x 165mm. The tool is 3mm Diam Ball Nose End Mill. What would the recommended stepover size be, to create a detailed finish.eg - 0.2mm? Obviously the smaller the stepover the longer the machine time,but detail is …
So I'm delveing into thread milling and I'm starting to understand the concepts of Pitch offset diameter and Major and Minor diameter but what I don't understand is how to calculate my stepover when doing multiple passes. I'm doing fairley small threads 8-36 and 4-40 so I want to do work the thread mill out in 3-5(?) passes with an additional …
In the images below we'll use a stepover equal to 1/10, 1/5, and 1/3 of the tool diameter to show this correlation. To put real numbers on this, that would be equavalent to a .012, .025, and .042″ stepover for a .125″ ball mill. Stepover =1/10 …
Remember, the part of the ball near the axis moves slowly. A smaller ball interpolated exposes more of the surface to a faster moving cutter, leading to a better finish. But, the smaller cutter can flex more. …

What is Chip Load? Meaning #1 – How Chip load is used in milling catalogs, and by most machinists. The maximum load that the cutting edge of a specific milling cutter (or indexable insert) can withstand without yielding or having a very short tool-life.. The chip load is specified in mm/tooth or Inch per tooth (IPT) units.
